I'm thinking about buying a Nagaoka Seisakusho 4x5 that appears to be in great shape but there just isn't much info on the web about these cameras. The few mentions in this forum all seem pretty positive from people who have/had them. Can anyone tell me the min and max bellows draw or the shortest and longest lenses that can be used (without resorting to a recessed lense board)? Also, I assume the vertical/horizontal orientation of the back can be changed, if so what is involved there. Thanks in advance for any responses.
